I've been using it for almost a month. It's my first experience with a WM phone, so as everyone knows the OS is not the userfriendliest one, though plenty of software on the net. Aside from that... the phone's strong features (imho) are: looks, build quality, UI, dimensions & weight, display. The main shortcomings (at least for me) are: battery time, lack of 3.5 mm audio jack, camera (both usability and picture quality are not the best on the market), vibration and ringing volume is below average - it's quite easy to miss a call being even not in a very noisy environment (maybe trying other ringing melodies will help, haven't mood for that yet :)). What else... by far it's been stable - been no rebootings or freezes, though i've not been into installing or other heavy loading that much. However, the CPU speed is far from perfect, it's ok but I wouldn't complain if it was a bit faster. Telephony's been ok.
